Scientists are working on a new technique to kill cancer cells by zapping them
with ultrahigh-energy (in the range of 1.00×1012 W) pulses of light that last for
an extremely short time (a few nanoseconds). These short pulses scramble the
interior of a cell without causing it to explode, as long pulses would do. We can
model a typical such cell as a disk 5.00 μm in diameter, with the pulse lasting
for 4.00 ns with an average power of 2.00×1012 W. We shall assume that the
energy is spread uniformly over the faces of 100 cells for each pulse.

Electromagnetic waves can propagate through a vacuum.
The speed of electromagnetic waves in a medium is always greater than the speed of light in vacuum.
Electromagnetic waves can exhibit both particle-like and wave-like properties.
The energy carried by an electromagnetic wave is directly proportional to its frequency.
The electromagnetic spectrum encompasses a wide range of wavelengths, from radio waves to gamma rays.

Two astronauts are 1.60 m apart in their spaceship. One speaks to the other. The conversation is transmitted to earth via
electromagnetic waves. The time it takes for sound waves to travel at 343 m/s through the air between the astronauts equals the time
it takes for the electromagnetic waves to travel to the earth. How far away from the earth is the spaceship?
